Original Filed Feb. 15, 1926 Patented Dec. 1, 1931 UNITED STATES- PATENT OFFICE ROBERT 3'. RICE, OF JOHNSON CITY, NEW YORK, ASSIGNOR TO UNITED SHOE MACHINERY CORPORATION, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY nas'rme MACHINE Driginal application filed February 15, 1926, Serial No. 88,270. Divided and this application filed October 2, 1929. SeriaI'No. 396,765.

This invention relates'to improvements in machines for use in the manufacture of shoes and is illustrated herein as embodied in a machine for lasting pre-welted shoes, that is shoes in the manufacture of which the welt is attached to the upper before the upper is lasted.

It is an object of the presentinvention to provide an improved machinefor working 1 the upper of a pref-weltedshoe into lasted relation to an insole and a last'on which the insole is mounted. \Vhile the illustrated division, it should be understood that it may also be used for other purposes;

A feature of the invention comprises means illustrated as a pair of gripper jaws adjacent to the fastening inserting instrumentalities of the machine for gripping the welt of a pre-welted shoe upper and holding the welt while the upper is worked into lasted relation to the insole and last and while a fastening is inserted to secure the upper. in lasted relation. Preferably and as illustrated the sole gripping means andthe fastening inserting instrumentalities are controlled by a single controller the displacement of which is effective first to operate the aws and thereafter to cause the insertion of a fastening.

Withthe above and other objects and fea" tures in view the invention will now be described withreference to the accompanying drawings and pointed out in the claims.

In the drawings: p v

Fig. 1 is a side elevation of the head of a machine embodying the present invention; and

Fig. 2 is a fragmentaryview on a larger scale showing the manner in which a shoe upper is held at the time a fastening is in-v serted to secure the .upper in lasted relation to the insole and last. a

In Fig. 2, the numeral 2.indicates the insole and 4 a filler piece of a pre-welted shoe,

also to the inner surface of the marginal por- I tion of the shoe upper 8 and to the edge of the shoe upper and welt 10. After the cement has been allowed to dry the insole 2 and filler 4 are secured to a last indicated at 11. The margin of the upper is then worked into lasted relation to the insole and the last is temporarily secured in that position by tacks. The illustrated machine is well adapted to perform this lasting operation.

Fig. 1 discloses the head of themachine,

which is atacker of the type disclosed in Letters Patent of the United States, No. 1,106,393, granted October 11, 1914 on an application of Fred L. Mackenzie, provided, however, with gripping means adjacent to the nozzle of the tacker and with a controller for actuating the gripping means and for thereafter causing the actuating of the tack inserting instrumentalities. The details of the tack inserting instrumentalities form no part of the present invention and it'is accordingly unnecessary to describe them at length herein. For a fuller. description of those portions of the machine. reference may be had to saidLetters, Patent. Briefly, the mechanism comprises a driver 30 carried by a driver bar 32 arranged to slidevertically in a guideway in the front part of the head 34. of the machine, the driver bar 32 being lifted against the tensionv of a spring by a lifting cam ,on the front end of the main shaft 36. The driving shaft is driven from a loose pulley 38 which may be clutched to the shaft at the will of the operator by suitable clutchmechanism controlled by a treadle 39 at thelower end of a treadle rod 40, as described in said patent. A tack pot 42 supplies tacks to a raceway 44 which conducts them to a'point adjacentto the nozzle 26 where they are separated one by one and delivered to the tacker nozzle 26 by suitable i 7 china. and; a movable jaw 2 L- attachedi to. a; levenfiO iulcrumed at: 52130 the plateASL The;

tack separating mechanism 46 such as thatdisclosed in United States Letters Patent No. 1,312,557, granted August 12, 1919, on an application of Fred L. Mackenzie.

In accordance with my invention the machine is;provided with a fixed jaw. 22, shown as supported on a plate 48, introduced between the head and the column of'the ma lever 50 has along resilient rearward extension 53 lying in the path of movement of a screw=54 adjustably threaded through a block 56 which is attachecl'tothe treadle r0d40 sothat' during the initial downward movement of the treadle 39 the aw 24; will be caused to approach. the jaw 22; The welt having. been thus seizedbetweenthe ja'ws,.the shoemay. be: manipulated,-. as indicated in.
